But alerting users is what triggers the behavior in (some) markup generator developers that we're trying to avoid triggering! I expect that the kind of the markup generator developers who wanted to silence HTML4 validators with alt="" would want to make this warning go away, too, so I expect this proposal would not yield a worthwhile benefit compared to going back to the HTML4 situation but would add complexity on the way. That is to say, I think this compromise is worse than either Ted's proposal or making validators whine about the absence of the alt attribute as with HTML4. -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
